Iron Ore Processing for the Blast Furnace The iron ore concentrate is now mixed and ready for the pelletizing process Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets in much the same manner that one rolls a snowball to make a pellet about the size of a marble between 1

Treatment of iron concentrate slurry to improve filtration

Aug 15 1978An improved process for filter dewatering of an iron ore concentrate slurry produced from iron ore by selective flocculation followed by flotation wherein acid and then a surface tension reducing agent of the sulfosuccinate class is added to the concentrate slurry before the slurry is filtered

Conventional vacuum filtration was previously used for dewatering of iron-ore product but with changing product quality requirements and declining ore grades compounded by the complexity of mineralogy and increased energy costs alternative more efficient dewatering solutions are being sought

The influence of certain surfactants on the dewatering of fine iron ore sludge flocculated with anionic flocculants has been investigated in a laboratory-scale vacuum filtration unit The filtration data have been used in calculating the cake parameters from an integrated form of Darcy's law
